Take it easy man, I haven't been in school for years and I don't calculate the circumference on a daily basis. I took university calculus and passed.

If you're not using that kind of math everyday, it's so easy to forget it. And there are a lot of people terrible at math but everyone has their strengths and their weaknesses... As proven by the many, many users on FML who don't know how to spell. Who knows, they could be a genius in another knowledgable subject. :)

Agree with 61. Especially since I can remember the equations to most dimensions of a circle, but which goes to which escapes me Pi(r)^2, 2(pi)r, dammit isnt there a 3rd?

Circumference: Perimeter of a circle. Diameter: Width of a circle. Radius: Half the width of a circle. Area: Area of a circle. Hope this clears it up.

The distance around a circle is called the circumference. The distance across a circle through the center is called the diameter. jesus, this is so fucking easy.

#61 is correct... I'm terrible at mental maths, and can't remember things I've done from last year, but I still get decent grades. I think it might be the way of teaching these days... You are taught to pass exams, not to be good at maths. I remember what I need to pass, and then i discard that information... Then if I need it again i re-learn it.

That sucks and all, but I wouldn't give someone who doesn't know the circumference of a circle a job. That's 6th grader math.

105-I'm pretty sure it's 4/3, not 3/4. Also, the surface area is easier, since you just get the area of the circle (r^2*pi) and then multiply by 2.

Didn't know they installed classrooms in kitchens yes days.. But yes I'd agree, circumference is a third-grade question. Grade seven would be the area of three-dimensional objects.

I did NOT learn the circumference of a circle in third grade. And I was in faster paced classes at a higher level...

Not every third grade class in America learns about circumference. I learned about it in 6th grade. Every part in the USA has different educational standards for that grade and district. Just because people didn't learn about circunferences in third grade does not make them slow........

No it's more like 6 or 7 th grade. My son is in the 4th grade and they don't study pi they have touched on finding the area of different shapes.

you'd have to be a smartass third grader to be learning the circumference of a circle.. they definitely learn about decimals and multiplication! so i highly doubt you learned about pi and radius in third grade..

I volunteer in a third grade class and they definitely do not learn how to calculate the circumference of a circle. The highest they have studied geometry is classifying polygons according to the number of sides. Many of them are still learning their times tables, so calculating circumference is out of the question

DocBastard - apparently she's a genius according to her profile. I think most people know the difference between "you're" and "your" but they are just too lazy.

I learned it in eighth grade and i'm two years ahead in math. I guess you learning it in third grade makes you that much smarter, huh?

Guys, mind you, people from all around the globe are commenting. Education varies so greatly, don't even worry about it.

Uh no. It was taught in 8th grade here. I covered it in 4th but I was in the advance class. My peers never were taught it til 8th. I know some places cover it in 6th or 7th grade, but certainly not before that.

Reply

I didn't learn that till Year 8 (about grade 7) and I've always been in top set for lessons. You may hear about it in grade 3 but certainly not use pi till around 6th grade.

Lmao! It's alright, Awsumuzzie, we sometimes miss part of the post, occasionally. Thumbs up for your self-flogging though. ;)

118- It's often shortened to 3.14 if not used as just pi. A lot easier then 3.14159265 or something even longer.

You wouldn't get the job, either, that's the area formula. Once, I got so nervous, I described in detail the circumcision of a circle. I didn't get the job, but they asked me to be their drinking buddy.

There's a difference between being good at math and being good at memorizing formulas. I'm surprised that the company couldn't see this. Personally, I couldn't tell you half the common knowledge formulas of area and volume simply because those are the kind of things you can easily look up. It's more important to have a good understanding of how to actually do the calculations. Maybe you should have told them that, OP.

#103, that sounds like something my Maths teacher would say, especially since he doesn't count biology as a science! :P
